Frequent issue when using external display with my HP Spectre x360 (13-ac003nf)

[NicolasFagart]

I use often external monitors for my HP Spectre notebook. And it happens very often that after about 20 min of work, suddenly the screens (both laptop and external during) frozen 1 sec, then black during few seconds and then it come back. It seems that it started to occur after a Windows update 1.5 to 2  years ago. And it appears more and more often. Some times it happens even 3 times in same minute... It becomes very hard to work and concentrate.

Furthermore, it creates problems for some applications that loose the image (when linked to graphical resources, like WebGL on browsers, Google Maps must be restarted for instance after each event like that).

I think it happens mostly when I'm using external display, but not sure it is linked only to that. Even without external display some times the image blink, but very quickly. When I have an external computer it takes 3 to 10 seconds to come back.

I tried to update and check the drivers, all seem up to date.

Let's try these steps -

2) In Device Manager, expand Display Adapter. 
3) Right-click on the Display Adapter, and then select Uninstall device > Delete the driver software for this device check box > Uninstall.
4) Restart the computer.

Hello,

Thanks for your messages,

I tried the first advise: I deleted the driver, downloaded and reinstalled the BIOS with the given link.

Unfortunately I did not have time to work a lot on my laptop since that moment, but it seems that it has fixed the issue !

I need to test a bit longer because the problem was appearing not regularly and some days did not happen other days it was happening many times.

Hopefully it will be fixed and I'll "accept the solution".

Thanks a lot !
